I tried to create a map too big (1071X691) and now i cant enter my game: out of memory

I was trying to configurate a campaign map to move players through the world, but it crashed and i cant return. There is any form to recover my campaign? Otherwise i will lose everything.

This sort of problem is precisely what the ticket system is for.  In the top right go to your account and then Help Center and submit a ticket.  

Hi Bruno, You can also try to mitigate the problem yourself, if the player flag is not on the map page in question. Create a  Dummy Account  and promote it to GM. It should load into the game on the player flag page, circumventing the map issue. The Dummy Account can then delete said page, allowing your master account back in. Otherwise, your best bet is to file a  Help Center Request  as DM Eddie suggests.
